摘要

The residents lived in the cold areas such as Harbin generally experience a residence time of approximately 6 months in chilly winter without frequent natural ventilation. To find out the influence of a short period of ventilation on the indoor formaldehyde concentration inside a new building, an investigation was conducted for the instance of twice ventilation in a day through window opening. The results showed that the indoor formaldehyde concentration increased with time after closing the window and followed an exponential function of C=C_0exp(-bt+(a+C_w)[1-exp(-bt] with correlation coefficient (R~2) of 0.945～0.999, based on the calculations for 14 groups of measurement data. The developed equation can be used to estimate the emission rate of indoor formaldehyde sources and the air exchange rate of the test room simultaneously.
